In the days after riding huge distances, my body has three reactions:
1. Holy crap I’m sore, what just happened?
2. To prevent you from doing anything that ambitious again, I’m going to go into sleep mode every couple of hours and render the brain powerless to motivate action
3. In case you figure out a way around that, I’m going to require massive calorie intake every time you wake and every few hours, so if you decide to run a marathon or something I’ll be prepped

I feel pretty good considering I biked over 200m Saturday and was criminally undertrained.
